| Abstract | In silicon compounds the Si atoms are known to be fourfold coordinated in most cases. However, there are several cationic, anionic, and neutral molecular species containing hypercoordinated – i.e., fiveand sixfold coordinated (and in few cases even higher coordinated) – silicon atoms. This class of compounds ranges from long known stable inorganic species such as SiF6 2 to many different organometallic compounds with multidentate chelate ligands. Although this field has been known since the early nineteenth century and expanded significantly in the twentieth century, very interesting advances have been developed in the past decade. These include the extension of established synthesis routes to novel ligand systems via substitution, addition, and oxidative addition, among others. A number of new organic ligand systems have been successfully applied leading to unprecedented coordination modes of the silicon atoms. The structures of the obtained compounds have been analyzed thoroughly in many cases providing detailed insights into structure and bonding situations in hypercoordinated silicon complexes. Besides the classical silicon compounds with donor atoms such as H, C, Cl, F, O, and N, many novel examples with main group metal as well as transition metal atoms in the coordination sphere of silicon have been reported. |
